Abstract
(B, ) the utility model relates to an inspection shaft lid for shock attenuation formula among road engineering, its including the well frame that can fix at the inspection shaft oral area, be used for the closed well lid body of well frame's opening, wherein well frame's opening extends along inspection shaft degree of depth orientation and sets up, the well lid body can and be set up in well frame is filled in to well frame's opening on well frame's supporting part, the inspection shaft lid is still including setting up the rubber packing ring between supporting part and well lid body. The utility model discloses an under the buffering of rubber packing ring, the noise reduction also reduces the vibrations of inspection shaft lid simultaneously for the vehicle that covers at the inspection shaft that traveles passes through relatively smoothly, in addition, simple structure, it is convenient to implement, and with low costs. (B, )
Description
Technical field
The utility model belongs to road construction journey field, is specifically related to the inspection shaft lid for damping type in road engineering.
Background technology
At present, it is common that inspection shaft covers in life very, its mainly can be fixed on inspection shaft oral area well frame, for the manhole cover body that the opening of well frame is closed. When vehicle movement and when pressing through inspection shaft lid, not only produce vibrations and send noise, and inspection shaft lid will vibrations anti-pass to, on the vehicle travelled, causing slope, a kind of top sensation, cause the comfort level of driving lower.
Summary of the invention
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art, it is provided that the inspection shaft lid for damping type in road engineering of a kind of improvement.
For solving the problems of the technologies described above, the utility model takes following technical scheme:
A kind of inspection shaft lid for damping type in road engineering, it comprise can be fixed on inspection shaft oral area well frame, for by manhole cover body closed for the opening of well frame, wherein the opening of well frame is extended along inspection shaft depth direction, manhole cover body can be filled in well frame from the opening of well frame and set up in the carrying portion of well frame, and inspection shaft lid also comprises the rubber cradle being arranged between carrying portion and manhole cover body.
Preferably, carrying portion is also provided with caulking groove, rubber cradle comprise the fitting portion that can embed in caulking groove and emerge caulking groove and higher than the buffer part of carrying portion upper surface.
Further, the inner side-wall of well frame opening is close in the side of buffer part. It is convenient to the location of rubber cradle.
Specifically implement and preferred aspect according to one of the present utility model, the thickness of manhole cover body equals to subtract the thickness of carrying portion upper surface buffer part of emerging from carrying portion to the vertical range of well frame upper surface, when manhole cover body bears pressure, the elastic shrinkage of buffer part, the upper surface of manhole cover body and the upper surface of well frame are put down together.
In addition, opening is identical with manhole cover body shape, and common is square or circular.
Due to the enforcement of above technical scheme, the utility model compared with prior art tool have the following advantages:
The utility model, by, under the buffering of rubber cradle, reducing noise, also reduces the vibrations of inspection shaft lid simultaneously so that travel inspection shaft lid vehicle relative smoothly through, in addition, structure is simple, and it is convenient to implement, and cost is low.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in more detail.
Fig. 1 is the cross section cross-sectional schematic according to inspection shaft lid of the present utility model;
Wherein: 1, well frame; 10, carrying portion; 10a, caulking groove; 2, manhole cover body; 3, rubber cradle; 30, fitting portion; 31, buffer part.
Embodiment
As shown in Figure 1, according to the inspection shaft lid for damping type in road engineering of the present embodiment, it comprise can be fixed on inspection shaft oral area well frame 1, for by manhole cover body 2 closed for the opening of well frame 1, wherein the opening of well frame 1 is extended along inspection shaft depth direction, manhole cover body 2 can be filled in well frame 1 from the opening of well frame 1 and set up in the carrying portion 10 of well frame 1, and inspection shaft lid also comprises the rubber cradle 3 being arranged between carrying portion 10 and manhole cover body 2.
Carrying portion 11 is also provided with caulking groove 10a, rubber cradle 3 comprise the fitting portion 30 that can embed in caulking groove 10a and emerge caulking groove 10a and higher than the buffer part 31 of carrying portion 11 upper surface.
Further, buffer part 31 is close to the inner side-wall of well frame 1 opening.
The thickness of manhole cover body 2 equals the thickness that the vertical range from 11 to well frame 1 upper surface, carrying portion subtracts carrying portion 11 upper surface buffer part 31 of emerging, when manhole cover body 2 bears pressure, the elastic shrinkage of buffer part 31, the upper surface of manhole cover body 2 and the upper surface of well frame 1 are put down together.
In addition, opening is identical with manhole cover body 2 shape, and common is square or circular.
In sum, the utility model, by, under the buffering of rubber cradle, reducing noise, also reduces the vibrations of inspection shaft lid simultaneously so that travel inspection shaft lid vehicle relative smoothly through, in addition, structure is simple, and it is convenient to implement, and cost is low.
Above the utility model is described in detail; its object is to allow the personage being familiar with this art can understand content of the present utility model and implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to spirit of the present utility model change or modify, and all should be encompassed in protection domain of the present utility model.
